Matrx PB Heavy-Duty Back

The Invacare Matrx PB Heavy-Duty Back provides the positioning support and comfort of the standard Matrx PB Back in a wider, stronger configuration for users who require added capacity and larger wheelchair seating dimensions. With its 5″ contour depth, the PB Heavy-Duty Back delivers moderate-to-deep lateral trunk support to help improve seated stability, posture, and alignment while maintaining a practical, non-bulky profile for daily wheelchair use.

Built with a durable ABS shell and molded foam that wraps around the shell for added comfort and protection, the Matrx PB Heavy-Duty Back is designed to replace standard sling upholstery with a more supportive rigid backrest. Easy Set hardware allows depth, angle, and rotation adjustment, helping create a more secure and individualized setup for manual or power wheelchair users who need dependable heavy-duty postural support.

Heavy-Duty Positioning Support

The Matrx PB Heavy-Duty Back is designed for larger users who need reliable trunk support, improved seated stability, and a more structured wheelchair backrest. Its 5″ contour depth provides increased lateral contact around the trunk, helping reduce side-to-side movement and support a more aligned seated posture throughout the day.

This makes the PB Heavy-Duty Back a practical option for users who need stronger support than sling upholstery can offer, but who do not require the deeper positioning profile of a full deep-contour backrest.

Molded Foam Comfort & Support

The PB Heavy-Duty Back uses molded foam over a durable ABS shell to combine firm structural support with everyday comfort. The foam wraps around the shell edges to help reduce contact with hard surfaces and create a more protective seating interface.

For users who need added softness or pressure-sensitive comfort, an optional Visco foam upgrade may be available for increased immersion and cushioning.

Easy Set Hardware & Adjustability

The Matrx PB Heavy-Duty Back includes Easy Set mounting hardware designed to make installation and adjustment straightforward. The hardware allows the backrest to be adjusted for depth, angle, and rotation, helping providers fine-tune the backrest to the user’s posture, wheelchair frame, and support needs.

This adjustability helps create a more secure and functional seating setup for users who need heavy-duty support with individualized positioning.
